Bidens plant named &#39;KOIBID1346&#39;

ABSTRACT

A new and distinct cultivar of  Bidens  plant named ‘Koibid1346’, characterized by its compact, upright to somewhat outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; and single-type inflorescences with greyed orange-colored ray florets and yellow-colored disc florets.

Botanical designation: Bidens triplinervia.

Cultivar denomination: ‘KOIBID1346’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bidens plant, botanically known as Bidens triplinervia and hereinafter referred to by the name ‘Koibid1346’.

The new Bidens plant is a product of a planned breeding program conducted by the Inventor in Okayama-ken, Japan. The objective of the breeding program is to create new freely-branching Bidens plants with unique ray floret coloration.

The new Bidens plant originated from a self-pollination made by the Inventor in Okayama-ken, Japan in January, 2010 of Bidens triplinervia ‘K-SAIKA001’, not patented. The new Bidens plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled greenhouse environment in Okayama-ken, Japan in May, 2010.

Asexual reproduction of the new Bidens plant by vegetative cuttings in a controlled environment in Okayama-ken, Japan since June, 2010 has shown that the unique features of this new Bidens plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Bidens have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Koibid1346’. These characteristics in combination distinguish ‘Koibid1346’ as a new and distinct Bidens plant:

1. Compact, upright to somewhat outwardly spreading and mounding plant habit.

2. Vigorous growth habit.

3. Freely branching habit.

4. Early and freely flowering habit.

5. Long flowering period.

6. Single-type inflorescences with greyed orange-colored ray florets and yellow-colored disc florets.

Plants of the new Bidens differ primarily from plants of the parent, ‘K-SAIKA001’ in ray floret color as inflorescences of ‘K-SAIKA001’ have subdued orange and yellow bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Haflpare’, disclosed in U.S. Plant patent application Ser. No. 14/544,724. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed primarily from plants of ‘Haflpare’ in ray floret color as plants of ‘Haflpare’ have deep orange and yellow bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Haflrest’, disclosed in U.S. Plant patent application Ser. No. 14/544,725. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed primarily from plants of ‘Haflrest’ in ray floret color as plants of ‘Haflrest’ have dark orange-colored ray florets with yellow-colored margins.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Hafltibr’, disclosed in U.S. Plant patent application Ser. No. 14/544,732. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed primarily from plants of ‘Hafltibr’ in ray floret color as plants of ‘Hafltibr’ have orange-colored ray florets with orange red-colored stripes.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Hafltifrpu’, disclosed in U.S. Plant patent application Ser. No. 14/544,730. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed primarily from plants of ‘Hafltifrpu’ in ray floret color as plants of ‘Hafltifrpu’ have orange and yellow bi-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Hafltufr’, disclosed in U.S. Plant patent application Ser. No. 14/544,729. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed primarily from plants of ‘Hafltufr’ in ray floret color as plants of ‘Hafltufr’ have dark orange-colored ray florets with yellow to light yellow-colored apices.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Florbikano’, disclosed in U.S. Plant Pat. No. 25,087. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed primarily from plants of ‘Florbikano’ in ray floret color as plants of ‘Florbikano’ have dark orange and yellow orange bi-colored ray florets.

Plants of the new Bidens can also be compared to plants of Bidens triplinervia ‘Yellow Charm’, not patented. In side-by-side comparisons conducted in Okayama-ken, Japan, plants of the new Bidens differed primarily from plants of ‘Yellow Charm’ in the following characteristics:

-   -   1. Plants of the new Bidens were larger than plants of ‘Yellow         Charm’.     -   2. Plants of the new Bidens were more outwardly spreading and         mounding than and not as upright as plants of ‘Yellow Charm’.     -   3. Plants of the new Bidens had narrower and darker         green-colored leaves than plants of ‘Yellow Charm’.     -   4. Plants of the new Bidens and ‘Yellow Charm’ differed in ray         floret color as plants of ‘Yellow Charm’ had solid         yellow-colored ray florets.     -   5. Plants of the new Bidens were more high temperature-tolerant         than plants of ‘Yellow Charm’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 10-cm containers during the summer in a polyethylene-covered greenhouse in Bonsall, Calif. and under cultural practices which approximate those generally used in commercial Bidens production. During the production of the plants, day temperatures averaged 27° C., night temperatures averaged 18° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched one time and were six weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
